巨细胞动脉炎(GCA)是一种炎性颅和/或颅外血管炎。虽然颅骨GCA被广泛认可,颅外GCA由于其非特异性和非典型表现而被低估.我们报告了在手术二尖瓣修复期间偶然发现的无症状颅外GCA伴上升胸主动脉病的病例。(难度等级:中级。).
Giant cell arteritis (GCA) is an inflammatory cranial and/or extracranial vasculitis. Although cranial GCA is widely recognized, extracranial GCA is underdiagnosed because of its nonspecific and atypical presentations. We report a case of asymptomatic extracranial GCA with ascending thoracic aortopathy discovered incidentally during surgical mitral valve repair. (Level of Difficulty: Intermediate.).
